MANAGEMENT OF CHEMICALS in APS SCIENCE LABORATORIES Environmental Compliance Branch Revised July 2013 Management of Chemicals in Science Laboratories Introduction This packet contains APS Guidelines for Management of Chemicals in science departments and is being provided to the science teachers in the K-8, Middle and High Schools. It contains information required by the Colorado Department of Public Health and Environment (CDPHE), Consumer Protection Division, outlined in the document Rules and Regulations Governing Schools in the State of Colorado. Additional information about the rules and regulations may be obtained by visiting the Division of Environmental Health & Sustainability’s web page at www.cdphe.state.co.us/cp/.

In addition to following the District’s regular purchasing procedures, an employee must reference three chemical lists published by the CDPHE; Appendix A - Prohibited Chemicals List, Appendix B - Restricted Chemicals List, and Appendix B2 - Restricted Chemicals Teacher Demonstration Use Only List. These lists can be found in Attachment C of this packet. See below for further explanation of each list. Appendix A - Prohibited Chemicals List - Items on this list may not be stored or used in the schools. Appendix B - Restricted Chemicals List - Items on this list are allowed, although some have a quantity limit indicated in parenthesis after the chemical name. A round yellow sticker and a CDPHE Appendix B label will be placed on these containers to identify them. Appendix B2 - Restricted Chemicals Teacher Demonstration Only List - Items on this list may only be used by the instructor for demonstration purposes and have quantity limits in parenthesis after the chemical name. Students are not allowed to handle these chemicals. A round red sticker and a CDPHE Appendix B2 label will be placed on these containers to identify them as demonstration use only. See Appendix B2 List. Further clarification has been provided by CDPHE regarding prohibited and restricted chemicals list when they are listed as an ingredient in a product or were part of a solid object or equipment that are used for demonstration or other instructional purposes. DOES THE PROHIBITED AND RESTRICTED LIST APPLY TO CHEMICALS LISTED AS INGREDIENTS ON A PRODUCT LABEL? The rulemaking process did not evaluate these chemicals when they occur as an ingredient in a product generally available to the public or were part of solid objects or equipment. Since adoption of the prohibited and restricted chemical lists, questions have been raised concerning the applicability to products where the chemical may occur as an ingredient but is not the sole active ingredient, or may be in low concentrations. The applicability of the lists to the occurrence of the chemicals in solid objects used for instructional purposes such as rock and mineral specimens and glazes on ceramics has also been questioned. Products that contain chemicals included in the prohibited or restricted lists that are not in a nearly pure form (or dilutions) are not subject to those lists. However, such products are subject to the regulations in “Chapter 6 – Equipment or Supplies” or other portions of “Chapter 8 - Laboratory, Industrial, Art, and Vocational Hazards” regarding safe management and use. 4 DOES THE PROHIBITED AND RESTRICTED LIST APPLY TO CHEMICALS THAT ARE INCORPORATED INTO SOLID OBJECTS USED FOR DEMONSTRATION PURPOSES? The prohibited or restricted chemical lists do not apply where the chemicals are incorporated into solid objects that are used for demonstration or other instructional purposes. These types of instructional supplies are regulated under other provisions of “Chapter 8 - Laboratory, Industrial, Art, and Vocational Hazards.” Some instrument check sources, and mineral and rock specimens may contain uranium, arsenic, or other chemicals on the prohibited or restricted lists. Such solid materials should be used under controlled conditions and following appropriate procedures regarding safe handling and controlled storage. Other solid objects that have been noted as containing prohibited or restricted chemicals are porcelain or pottery that have glazes containing uranium or chromium pigments, demonstration devices, such as science test kits and cloud chambers, and similar objects. These materials are not subject to the prohibition; however, such materials should be covered by written procedures for safe handling and controlled storage. Under no circumstances are donated hazardous materials to be received unless prior written approval for such materials has been given by the Environmental Compliance Branch. The following should be evaluated prior to purchasing hazardous materials: Is there a need for the material? Is it currently on the chemical inventory? What are the hazards? Is there a non-hazardous material or a less hazardous substitute? Are the quantities being purchased justifiable? What is the stability and shelf life of the hazards? Is suitable and sufficient storage available? Does the material require special disposal considerations? Is the material on the Appendix A or Appendix B2 product list? When new chemicals are received, it is important to immediately open the packaging and inspect the container. Containers should be received in good condition, sealed, properly labeled, and with a material safety data sheet. Immediately place the date received label, ChemLog label and CDPHE labels on the container and place it in the appropriate storage shelf, and write the quantity and date received of the new product on the chemical inventory sheet posted in the storeroom. If containers are found to be leaking or damaged, call the Environmental Compliance Branch for assistance with spill response and disposal. If the containers have missing labels, unreadable labels, or do not have a material safety data sheet, call the supplier to request that the appropriate label or material safety data sheet be sent. For additional information see Aurora Public Schools District policy and regulation EBAB and EBAB-R. 5 General Rules and Procedures Wear appropriate clothing and use personal protective equipment (PPE), such as safety glasses, when working in the laboratory to avoid unnecessary exposure to the chemicals. Know the location and use of all safety equipment (fire extinguisher, eye/face wash station, safety shower, fire blankets, chemical spill kits, emergency numbers and phone, etc). Know the evacuation procedures in case of an emergency or safety drill during a laboratory experiment; containers must be closed, gas valves turned off, fume hoods and any electrical equipment turned off. Follow safe use and handling of glassware procedures. Never use glassware that is scored, chipped or broken. Dispose of glassware in appropriate container. Ensure defective equipment is not used until repaired or replaced and unsafe condition is corrected. No eating or drinking in chemical areas. Follow good housekeeping in all laboratory areas. Clean up work areas and return equipment and supplies to their proper place. Clean up any debris or mess, another person may not know what the white powder on the counter contains. Inventory and Tracking Many products stored and used in a school contain chemicals that can have health and safety hazards associated with them. When these products are identified, stored, and handled properly these hazards can be reduced. Chemical inventories are one measure taken as part of a comprehensive program used to manage chemicals used in the District. Science Chemical Inventories The science chemical inventory is a list of all hazardous products used and stored in the science area at each site. The Environmental Compliance Branch is responsible for determining safe storage, federal and state chemical reporting requirements and developing a Material Safety Data Sheet (MSDS) tracking system from the chemical inventories. The science chemical storerooms have been thoroughly inspected and the potentially unstable chemicals were identified and removed. The remaining chemicals were inventoried, segregated, labeled and
